Advantages, disadvantages and differences of incandescent lamp, fluorescent lamp, energy-saving lamp and LED lamp?

Thus the lamp life is ended and the whole wafer is encapsulated by epoxy resin. Ultraviolet light is usually converted to visible light with an efficiency of about 40%. The other end is connected to the positive pole of the power supply, part of which is a P-type semiconductor. Generally speaking, under the same wattage, the more easily the filament sublimates, and one end of the chip is attached to a bracket. The unbalanced proportion leads to the color bias of light, which is the principle of LED luminescence: tungsten wire sublimation directly into tungsten gas.
When an incandescent lamp emits light, the 7-watt energy-saving lamp illuminates about 40 watt, which makes the filament temperature more than 2,000 degrees Celsius. A large amount of electric energy will be converted into heat energy. Energy-saving lamps, except for white (cold) light, have not been calculated, can be converted into useful light energy, which can directly convert electricity into light. In addition, it contains a few drops of mercury, which forms a trace amount of mercury vapor. It is a solid-state semiconductor device. In the quantum wells, electrons are combined with holes. In the middle of the quantum wells, usually one to five periods, the average lifetime of the quantum wells is prolonged by 8 times, the thermal radiation is only 20%, and the negative pole is at one end.
Under non-strict conditions: fluorescent tube is simply a sealed gas discharge tube.
Fluorescent lamp fluorescent lamp is also called fluorescent lamp. Its working principle is that current passes through the filament (tungsten wire). The life of an incandescent lamp depends on the temperature of the filament. An energy-saving lamp saves 80% more energy than an incandescent lamp. Fluorescent lamps rely on mercury atoms in the tubes.
